Best annuity product for 2018

I would like to invest 20Lax and get immediate annuity
Me+wife(100%)+ 100% return of capital (No link with any kind of insurance)
I notice LIC seems to have withdrawn their Jeeevan Akshay
I noticed HDFC Life,ICICI Prudential, SBI Life by googling
I already applied online and found below information
HDFC 10798 Rs per month
ICICI 10210 Rs
SBI Life 9230Rs
1)Who are the other market players?
2)Would you have a list or a site comparing these and any other companies
3)Would you recommend any other form of investments?
Have a few more Qs..but I will come to that as the discussion or advice starts
